The Expanded Role of Chitosan in Localized Antimicrobial Therapy
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-08)Chitosan is one of the most studied natural origin polymers for biomedical applications. This review focuses on the potential of chitosan in localized antimicrobial therapy to address the challenges of current rising antimicrobial resistance. Due to its mucoadhesiveness, chitosan offers the opportunity to prolong the formulation residence time at mucosal sites; its wound healing properties open ... -
Development of a novel beta-glucan supplemented hydrogel spray formulation and wound healing efficacy in a db/db diabetic mouse model
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-30)To relieve the severe economic and social burdens and patient suffering caused by the increasing incidence of chronic wounds, more effective treatments are urgently needed. In this study, we focused on developing a novel sprayable wound dressing with the active ingredient β-1,3/1,6-glucan (βG). Since βG is already available as the active ingredient in a commercial wound healing product provided as ... -

Antimicrobial resistance acquisition via natural transformation: context is everything
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-26)Natural transformation is a process where bacterial cells actively take up free DNA from the environment and recombine it into their genome or reconvert it into extra-chromosomal genetic elements. Although this mechanism is known to mediate the uptake of antibiotic resistance determinants in a range of human pathogens, its importance in the spread of antimicrobial resistance is not always appreciated. ... -
Nanomedicines for the topical treatment of vulvovaginal infections: Addressing the challenges of antimicrobial resistance
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-30)Recent years have, surprisingly, witnessed an increase in incidence of sexually transmitted infections (STIs). At the same time, antimicrobial therapy came under the threat of ever rising antimicrobial resistance (AMR), resulting in STIs with extremely limited therapy options. In this review, we addressed the challenges of treating vaginal infections in an era of AMR. We focused on published work ... -
Electrospun Amphiphilic Nanofibers as Templates for In Situ Preparation of Chloramphenicol-Loaded Liposomes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-20)The hydration of phospholipids, electrospun into polymeric nanofibers and used as templates for liposome formation, offers pharmaceutical advantages as it avoids the storage of liposomes as aqueous dispersions. The objective of the present study was to electrospin and characterize amphiphilic nanofibers as templates for the preparation of antibiotic-loaded liposomes and compare this method with ... -
Bacterial evolution on demand
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-06)Bacteria carry antibiotic resistant genes on movable sections of DNA that allow them to select the relevant genes on demand. -
Stanozolol-N-glucuronide metabolites in human urine samples as suitable targets in terms of routine anti-doping analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-05)The exogenous anabolic-androgenic steroid (AAS) stanozolol stays one of the most detected substances in professional sports. Its detection is a fundamental part of doping analysis, and the analysis of this steroid has been intensively investigated for a long time. This contribution to the detection of stanozolol doping describes for the first time the unambiguous proof for the existence of ... -
Identifying the drivers of multidrug-resistant Klebsiella pneumoniae at a European level
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-29)Beta-lactam- and in particular carbapenem-resistant Enterobacteriaceae represent a major public health threat. Despite strong variation of resistance across geographical settings, there is limited understanding of the underlying drivers. To assess these drivers, we developed a transmission model of cephalosporin- and carbapenem-resistant <i>Klebsiella pneumoniae</i>. The model is parameterized using ... -
Amphipathic Barbiturates as Mimics of Antimicrobial Peptides and the Marine Natural Products Eusynstyelamides with Activity against Multi-resistant Clinical Isolates
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-27)We report a series of synthetic cationic amphipathic barbiturates inspired by the pharmacophore model of small antimicrobial peptides (AMPs) and the marine antimicrobials eusynstyelamides. These N,N′-dialkylated-5,5-disubstituted barbiturates consist of an achiral barbiturate scaffold with two cationic groups and two lipophilic side chains. Minimum inhibitory concentrations of 2–8 μg/mL were achieved ... -
Liposomes-in-chitosan hydrogel boosts potential of chlorhexidine in biofilm eradication in vitro
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-16)Successful treatment of skin infections requires eradication of biofilms found in up to 90 % of all chronic wounds, causing delayed healing and increased morbidity. We hypothesized that chitosan hydrogel boosts the activity of liposomally-associated membrane active antimicrobials (MAA) and could potentially improve bacterial and biofilm eradication. Therefore, liposomes (∼300 nm) bearing chlorhexidine ... -
Chitosomes-In-Chitosan Hydrogel for Acute Skin Injuries: Prevention and Infection Control
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-12)Burns and other skin injuries are growing concerns as well as challenges in an era of antimicrobial resistance. Novel treatment options to improve the prevention and eradication of infectious skin biofilm-producing pathogens, while enhancing wound healing, are urgently needed for the timely treatment of infection-prone injuries. Treatment of acute skin injuries requires tailoring of formulation to ... -

Piggybacking on Niche Adaptation Improves the Maintenance of Multidrug-Resistance Plasmids
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-24)The persistence of plasmids in bacterial populations represents a puzzling evolutionary problem with serious clinical implications due to their role in the ongoing antibiotic resistance crisis. Recently, major advancements have been made toward resolving this “plasmid paradox” but mainly in a nonclinical context. Here, we propose an additional explanation for the maintenance of multidrug‐resistance ... -
From Paper to E-Prescribing of Multidose Drug Dispensing: A Qualitative Study of Workflow in a Community Care Setting
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-16)E-prescribing is now widespread and, in some countries, has completely replaced paper prescriptions. In Norway, almost all prescribing is electronic, except for multidose drug dispensing (MDD), which is still sent to the pharmacy by fax or ordinary mail. MDD is an adherence aid used by one-third of all patients receiving home care services. In this paper, we present results from a qualitative study ... -
